Industrial units require industrial materials.

That's why we begin with a minimum 16-gauge steel, standard in all of our cabinets. Commercial grade 20-gauge steel just cannot compare in the severe environments found in many refineries and mining operations.

Galvanized Steel

16-Gauge Hot-Dipped Galvanized Steel

Standard corrosion protection for long life.

Galvanized steel is the standard industry material for outdoor products. Untreated metals such as steel are prone to rusting. Using zinc, the galvanizing process forms a metallurgical bond with raw steel, coating the steel with zinc that resists rusting under normal conditions. Galvanizing provides a structural element that requires very little maintenance, and is intrinsically resistant to surface damage.

Specific Systems then goes a step beyond galvanizing, by including powder coating as standard on all galvanized units. The hot-dipped galvanized steel is trimmed to size, formed, and powder coated in Specific Systems facility before being assembled. Powder coat is available in the five standard colors shown below, with custom colors available upon request for a small additional charge.

Galvanized steel is the economical choice when the extra corrosion protection of stainless steel is unnecessary. As with all Specific Systems products, galvanized steel units are prepared for a long service life.

Specific Systems standard cabinets are composed of 16-gauge hot-dipped galvanized steel that has been powder coated to a thickness of 3-4 mils in one of several colors. The extra coating helps separate the galvanized steel from the environment, connecting screws, and internal components of the unit.

Internal shelving of all galvanized units are manufactured using 12-gauge galvanized steel. All units also include a stainless steel drain pan to prevent corrosion in the most vulnerable internal area of the unit. All connections are made using stainless steel screws, which are intrinsically corrosion resistant themselves, and do not create an electrical current with the galvanized steel.

304 Stainless Steel

16-Gauge Type 304 Stainless Steel

Upgraded corrosion protection for extended life.

One of the most corrosion resistant and commonly used type of stainless steel, Type 304 is in the family of austenitic alloys of stainless steel that exhibits excellent corrosion resitant properties, especially when maintained annually. Type 304 stainless is resistant to oxidation in non-chloride environments, and is typically used in applications such as on-shore refineries and production facilities where corrosion is likely.

Type 304 stainless steel is standard 18/8, designating the inclusion of 18% chromium and 8% nickel, with a mixture of other metals. The chromium, infused during manufacture of the material, creates an invisible layer on the surface of the steel to prevent rusting. Type 304 stainless steel is also non-magnetic. Stainless steel is 100% recyclable and has an extremely long useful life, so it is an excellent choice for companies looking to decrease their impact on the environment. Specific Systems Type 304 cabinets are constructed using 16-gauge type 304 stainless steel with a bright, unpolished 2B milled finish. This finish is smooth enough to resist particle adhesion and is easily maintained.

As a standard feature, 12-gauge type 304 stainless steel is used inside the cabinet as mounts for motors to increase the level of corrosion resistance throughout the unit. 304 stainless steel is also used in the manufacture of the standard drain pan in every unit.

316 Stainless Steel

16-Gauge Type 316 Stainless Steel

Our best protection against the elements.

Type 316 stainless steel is the most corrosion resistant of all metals and finishes offered by Specific Systems. Type 316 stainless steel is in the family of austenitic alloys of stainless steel that exhibits excellent corrosion resitant properties, especially when maintained annually. Like Type 304 stainless steel, Type 316 is resistant to oxidation in non-chloride environments, but offers an additonal level of corrosion resistance, specially designed for chloride and highly sulfuric environments.

Type 316 stainless steel is standard 18/10, designating the inclusion of 18% chromium and 10% nickel, with a mixture of other metals. The chromium, infused during manufacture of the material, creates an invisible layer on the surface of the steel to prevent rusting. What gives Type 316 stainless the extra corrosion resistance is the addition of molybdenum to the alloy, which helps to resist pitting and crevice corrosion sometimes found in Type 304. Type 316 stainless steel is also non-magnetic. Stainless steel is 100% recyclable and has an extremely long useful life, so it is an excellent choice for companies looking to decrease their impact on the environment. Specific Systems Type 316 cabinets are constructed using 16-gauge type 316 stainless steel with a bright, unpolished 2B milled finish. This finish is smooth enough to resist particle adhesion and is easily maintained.

As a standard feature, 12-gauge type 304 stainless steel is used inside the cabinet as mounts for motors to increase the level of corrosion resistance throughout the unit. 304 stainless steel is also used in the manufacture of the standard drain pan in every unit.

Aluminum

0.050" Aluminum Cabinet

Strong, lightweight option for mobile applications.

Used exclusively to lessen the weight of AirPak systems designed for mobile applications, 0.050 aluminum is used as a base and treated to the same corrosion-resistant powdercoating as our standard 16-gauge galvanized steel cabinets.

AirPak units utilizing aluminum cabinets are usually mounted on a skid manufactured from a thicker grade aluminum. Further, the bases are reinforced to minimize vibration in the condenser section, and additional bracing can be added to the sides of the units to provide mounting support.
